'Specification of .Letters Patent.Y

Patented Dec. 7, 1909.

Application filed April 10, 1909. Serial No. 489,060.

To allwhom 'it 'may concern: i

Be it known that I, EDWARD F. LINDSAY,

vprovide'a divided support and' insulator for electric conductors.

.uiotner object is to provide a separable supporter for electric conductors, so constructed that the insulator proper Willbe incased and shielded.

il. still further object of my invention is, to provide a support for electric conductors, arranged to hold the conductor Without tie wires, and prevent their slipping While suspended.

W ith these and other objects in view, the present invention consists in the combination and arrangement of `parts as Will be hereinafter more fully described and particularly pointed out in the appended claims, it being undor'stoochthat changes in the specific structure shown and described may` be made Within the scope of the claims without departing. from the spirit of the invention.

In the drawings forming a part of this specification, and in which like numerals of reference indicate similarA parts in the several. views7 Figure 1 is a perspective view of a separable insulatorv embodying my invention, Fig. 2 is a sectional view on line 2-'-2 of Fig. l. Fig. 3 is an end view, Fig. 4 is aA p face vievs7 of the holding member, Fig. 5 is a face view of the held member, Fig. shows the insulator secured to thelcross-tree of a telegraph pole, F ig` 7 shows the insulator secured to the side of a building, as a supporting bracket.

The aim of my invention is to providea cheaply constructed readily attachable holder. and insulator for electric conductors so constructed that the conductors may be readily secured or replaced, and which is especially adapted to be fastened onvertical surfaces.

In thevdrawings, 5 represents the main section ofthe casing as used in my invention, which has the beveled forwardly extending end 6, provided with the beveled under face i and used channeled block of Wood or other vsuitable Vmaterial and has the two oppositely 'posis tioned sides 8 v which have their inwardly positioned faces undercut' as shown in Fig.

3. The bevel faces 9 form in effect a dove.

tailed groove Within which is slidably held the 'concaved insulator` 10. This concaved insulator has its oppositelongitudinal edges 11, Which run parallel with the 'concavedl face 9', beveled as clearly disclosed in Fig. 3, 'so that the insulator which 'is made of glass or. other insulating material Will readily slide Within the holder -5 in. which it is frictionally held. The beveled `sides 8,

7. This section is inthe form ot a centrally 4 of the holder 5 at opposite -points are kprovided with `the recesses v13, While the glass female insulator 10 is transversely positioned Wire receiving grooveI 15,.-Whioh registers with the recesses 13.

The holder 5 may bemade of Wood, lfiber,l

metaLor any other suitable material.

Held upon the sides 8, 8 and against the bevel under face 7 of theholder 5 isthe cap plate 16, which forms a held member. This member `16 is of asize to snugly fit upon the holder 5 asdisclosed in Fig. 1. The rojec.-V

tion 6 forms the top of the holder W .en secured to support a conductor and overlap# ping the upper.- beveled end of the member 16 prevents any- Water creepin Adown between these two, holding mem ers. -This cap plate 16 also has its inner edges 17 bev.- eled, to, slidably receive the male insulator 20A having the convex face 21 whichv is also -traversed by a Wirereceving groove 22 registering with the "groove 15. These grooves 15 and 22 are of such aV size as tosnu ly reyc'eive the conductor. The sides of tlgi ecap late are recessed at opposite points as shown at 25, these recesses 25 re istering with thosev marked 13 Within the hol shown. Both of the glass insulators. are arranged to be frictiona ly held Within thecas'- inv' forming shielding holders.

The idea of incasing the insulators forms provided With the der 5 as an important part of my invention as it prevents mischievous parties' from breaking the same While at the same time preventingany Water, icefor snow covering them and` torming a circuit with the conductor held by these insulators. 'The top plate is also made of Wood, compressed fiber, or any other suitable material. The holding member 5 is secured by means of a nail A Which is driven through the upper projecting end 6 of the holder to securely support-the same. rlll-he held member after being secured to the hold-- may be .removed curely support the same.

' opposite positioned longitudinal edges proed with the fiat upper'shoulders' 0:, a, which the wire receiving grooves extend. The concave as wellas the convex faces of' i thesel glass insulators continue abruptly from these meeting shoulders a as shown in Fig. 3.

-From the foregoing itwill be seen that I have an incased insulator made in two separable sections between which the conductor is held against slipping, and from which the Y conductor can be readily removed. The lower sup orting screw or nail lil4 may also be.

f ma eto do service in supporting the two 25 glass insulating members, should these'members in any Way become loosened between the holders, though care must be taken that Vthese insulators will not slip down so far that the conductor will contact with the` holder and holding members which are not lmade fof insulating material..

".Havin thus described my said invention, what I c aim as'new and desire to secure by United States LettersPatent is: l

l. A holding member having an extending i y upper end provided with a beveled under face two oppositely positioned beveled edges, of a non-conductor having a concaved face and two beveled faces runnin parallel with said face and frictionally he d within said holding member, aeap plate having oppositely positioned bevel edges and an up- Maese per beveledlen'd resting below said extending end, and a bevelededged non-conductor having a convex face registering with said concave face and slidably held to said cap plate, each of said non-conductors having a transversely positioned wire receiving groove.

2. In combination,a holding member having beveled edges, a held member having .beveled edges secured to said holding member, each of said beveled edges having a recess, a concavebevelededge insulator held within said hlding member, a. bevel edgled vinsulator having a convex face held wit insaid held member, each of said insulators having a transversely positioned groove and A holding member having 4an extending upper end vprovided with beveled under face and two oppositely positioned beveled ledges, of a. non-conductor having a concaved face provided with two oppositely flat shoulders, the lon itudinal edges of said insulator beingI beve ed edged, aw'ire receivingslot traversin V the eoncaved face of said inrmeans to secure said held` member t0 said holding' member.

sulator, a he d member having oppositely .positioned beveled edges and an upper beveled end restin below said exten mg end, and a bevelede ged nonccnductor having a convex face registering wlth sald concave face and two oppositely positioned flat shoulders said insulatorjbeing slidably held within said held member, each of said members having a transversel f means 'to securel sait? members.

In testimon wheref I aix my signature EDWARD F. LINDSAY.'
